The first outbreak of Ascocbyta blight in commercial chickpea crops in Western Australia was detected in July 1999. By the end of 1999, over 7C crops were found to be infected. Due to difficulty in detecting low levels of the disease, it is expected that many parts of the wheatbelt that now appear free of the disease may have a low level of infection. Ian Pritchard reports on the disease symptoms, its spread, and the management principles now in place to minimise the impact of Ascocbyta blight for the 2000 season.
